How do I reset the tags in the ranger file browser?

I have made a small script to list all my tagged files with ranger with

--list-tagged-files=*

and put that list into another file (called todo). After a while I deleted and changed the name of some of the folders that still contained some tagged files. Then, when I ran ranger again, I saw that all my tags were gone and I had to re-tag them. Now, when I run my script, not only my currently tagged files are shown, but also the files that resided in the old folders that are potentially not accessible to me anymore. Now, I would like to know how I can reset the tags in ranger, so that I can re-tag my new files again, but only see those in my todo-file. I've checked the man page, but I could only find some

and

commands that I cannot use on files and diretories that I can't access anymore. Thanks in advance :)
